Drugs worth 1.94 million euro have been seized and two men have been arrested after a vehicle stop and several Garda searches.
Gardai from the National Drugs and Organised Crime Bureau intercepted the vehicle near Drogheda on Wednesday.
A number of simultaneous searches were carried out at a business and home in Drogheda and another home in north Dublin.
Cocaine and cannabis with an estimated potential street value of 1.94 million euro was seized.
Two men, in their 30s and 40s, were arrested on suspicion of facilitating and enhancing drug trafficking for a criminal organisation, and were detained at a Louth Garda station.
Gardai said the operation was a result of collaboration between the National Drugs and Organised Crime Bureau and the Police Service of Northern Ireland, aimed at organised crime activity in both jurisdictions.
Detective Chief Superintendent Seamus Boland said: “An Garda Siochana are committed, along with our partners in the Police Service of Northern Ireland, to prioritise the joint targeting of criminal organisations that attempt to exploit our land border, for serious criminal activity.
“Drug traffickers, and those that facilitate and enhance this activity, remain priority targets for our investigations, due to the destruction, violence and intimidation they cause in our communities.
“I encourage everyone to play their part, help us and report all information confidentially to the Garda Confidential Line at 1800 666 111.”
